SPECIFICATION forming part of Letters Patent No. 232,992, dated October 5, 1880.

Application filed August 10, 1880.

To tu whom it may concern Be it known that we, WILLIAM F. LO'rZ and- JOHN LEMON, ot' the city ot' London, in the county of Middlesex, England, have ljointly invented a new and useful Improvement in Lamp-Burners and we do hereby declare the f'ollowing to be a full and exact description thereof, reference being had to the accompanying drawings, making part ol'l this specication, and to the figures audletters of reference marked thereon, in which similar letters of reference indicate corresponding parts.

rlhis invention relates to a device for extinguishing a lamp by simply turning a key.

1t consists in a sliding tube surrounding the wick-tube, which is moved up and down upon the wick-tube by means oi' a lever-key, and having at its upper end a hinged wing operated by a spring which automatically closes down over the wick when said sliding tube is raised and automatically openswhen said tube is depressed.

In the accomiianying drawings wc have shown our invention applied, first, to a lamp with double wick-tubes, and, second, to a lamp with a single wick-tube.

Figure l is an elevation of the burner of a lamp with duplex wick-tube, which is above the oil-cup and below the detlecting-dome.

Fig. 2 is a vertical section of same in line y y of Fig. 3. Fig. 3 is a vertical section in line a: .fr of Fig. 2. Fig. 4c shows a modification to adapt our invention to a lamp with a single wick-tube.

Like letters indicate the same parts in all the figures.

fe will iirst give a detailed description of our invention as applied to a lamp with duplex wick-tubes.

A is the base of the burner, which is perforated in the usual manner. B B are the wicktubes. O C are the sliding extinguishingtubes, and c c are the extinguishing-wings hinged thereto. D is a shaft for operating the extinguishing-tubes. d is a curved lever rigidly attached to'said shaft, and d is a key on the end of said shaft for operating the same. E is a connecting-block between the sliding tubes C C, and rigidly attached to both. E is a slotted stud or stirrup depending from said (Model.)

block E, through which the curved lever d passes, and c is acylindrical stud screwedinto the upper side of said connecting-block E, and this stud c passes loosely through a horizontal plate, c, extending across between the sliding tubes, but not attached to either, so that it has a vertical movement between and independently of them; Between the block E and the plate c', and surrounding the stud e, is a spiral spring, f.

The extinguishingwings c c are bent inward at their bases below the pivots on which they turn, as shown at c in Figs. 2 and 4i, and said inwardly-projecting bases bear upon the horizontal plate c. Said inwardly-projecti ng bases may be formed by bending or striking up the lower ends of the wings c c or by soldering thereto strips ot' metal, as shown in the drawings.

From the shaft D a lever, d, Fig. 2, pro- 7ov jects laterally, to which a string, df., may be attached for operating the extinguisher when the lamp is in an elevated position.

The operation is as follows: When the lamp is burning the sliding tubes C C are depressed, 7 5 as shown in Fig. l. To extinguish the llame the shaft D is turned in the direction to elevate the curved lever d, which carries up the block E, and with it the sliding tubes to which it is attached. Vhen the horizontal plate e 8o rises nearly to the top of the wick-tubes the spiral spring, acting upon said plate c, forces it upward against the inwardly-projecting bases of the wings c c, and causes them to close suddenly over the wick-tubes, as shown 8 5 in Figs. 2 and 4t, and extinguish the flame. Vhen it is desired to relight the lamp the shaft D is turned in the direction to depress the curved lever d, which carries down the block E and the sliding tubes C G, causing the 9o wings c c to assume a vertical position, as shown in Fig. l.

To adapt our invention to a lamp with a single wick-tube slight modifications are made, as shown in Fi 0'. 4. In this case a plate, E, 95 extending horizontally from the sliding tube C and rigidly attached thereto, performs the function of the connecting-block E, (shown in the other gures,) and the L-shaped plate c performs the function ot' the plate c (shown roo in said other figures.) The vertical leg ot' said plate e passes through a slot in the plate E, which secures to it a correct vertical movement.

We do not limit ourselves to the use of the rock-shaft D, curved lever cl, and stirrup E to elevate and depress the sliding extinguishing'- tubes, as other well-known equivalent devices for similar purposes-as, for instance, a rack andpinion-maybesubstituted Withoutchanging the principle of our invention.

What we claim as our invention is- 1. In combination With duplex Wick-tubes, the sliding tubes C U, with the extinguishingwings c 0 hinged thereto, the sliding block E, ith stirrup E', vertical stud e, horizontal plate .spring f, shaft' D, and curved lever d, all

constructed, combined, and arranged to operate substantially as shown and described.

2. In combination with a single Wick-tube, the slidin g tube C, with extension-plate E attached thereto and extinguishing Win g c hinged thereto, plate e, stirrup E', vertical stud e, spring j', shaft D, and curved lever d, all constructed, combined, and arranged to operate substantially as set forth.

In testimonT that we claim the foregoing as our invention We have hereunto affixed our signatures in the presence of two Witnesses.
